7-aminocepha-losporanic acid (7-ACA), is described. The key feature of our method is based on the protection of the anino group as a Schiff base instead of the usual procedure based on the acylation of the amino group. The relative incapacity of 7-ACA derivatives to produce organic solutions with usual tertiary bases is easily overcome with bicyclic amidines. Catalytic amounts of these bases and N-trimethy
